It is very hard for me to understand how well you know his personality. I mean, I discover new personality characteristics every single day in my colleagues, my friends, my children and even my wife. Truly knowing someone takes years, lots of talks and experiences and close contact.What the heck is so hard to understand about I do NOT like his personality?
I doubt if you know Alaphilippe personally, or if you even know people who know him personally. I at least know some people who ride in his team. That could result in a possible bias that is favourable towards him, but I don't even dare to say anything about him, good or bad. I only know him from television and interviews. Just not enough to have an opinion, but my opinion about people I don't know is a bit biased towards 'positive' because I feel that everybody deserves a chance to give a first personal impression. I cannot 'unlike' someone before we haven't even met!
So to state that you don't like someone's personality, when you have never talked to that person, don't even understand what they are saying in their native language... It all like there is a massive barrier made mostly by a cultural difference, by not having face-to-face contact and by having massive prejudice.
